One recording. More ways to listen.

## From track to  
practice mix.

A focused workspace for separating, listening and keeping the parts you need.

01 / SEPARATE

### Start with your audio.

Choose a local recording and create four stems: vocals, drums, bass and other instruments. No recording upload is needed for separation.

02 / PRACTICE

### Find your balance.

Listen to each part. Use Level, Mute and Solo in Stem Mixer, or begin with a Practice Mix preset.

03 / EXPORT

### Take the mix with you.

Reopen projects in your local Library. Export individual stems, or use Export Mix to save your chosen balance.

Stem Mixer

## Hear the part.  
Leave room for yours.

Mute the vocals to sing along, or take out drums or bass to play your own part. Adjust the balance without changing your original stems.

Export Mix saves the full song with your Level, Mute and Solo settings in WAV, AIFF or FLAC. Master listening volume and the metronome are not included.

Results vary with the recording. Bleed between stems and separation artifacts can occur. Listen before using an export in a performance or production.

On your Mac

## Local audio.  
A clear boundary.

MixSift processes audio, waveforms and project contents on your Mac without uploading them for separation.

Downloading the app, purchases, Restore and access verification can need internet. Apple purchase services and any selected RevenueCat route are separate from audio processing.

A little room to play

## Your next practice mix  
starts with a track.

Two successful free splits are planned. Further splitting uses MixSift Pro; the final purchase options remain under review. Current localized pricing and terms will be shown in the app before purchase.
